|Postulate 1: State of a system
|A [[quantum state|system]] is completely specified at any one time by a [[Hilbert space]] vector.
|-
|Postulate 2: Observables of a system
|A [[observable|measurable]] quantity corresponds to an [[operational definition|operator]] with [[eigenvector]]s [[linear span|spanning]] the [[vector space|space]].
|-
|Postulate 3: Observation of a system
|Measuring a system applies the observable's operator to the system and the system [[Wave function collapse|collapses]] into the observed eigenvector.
|-
|Postulate 4: Probabilistic result of measurement
|The [[probability]] of observing an eigenvector is derived from the square of its [[wavefunction]].
|-
|Postulate 5: Time evolution of a system
|The way the wavefunction evolves over time is determined by [[Shrodinger's equation]].
